M10 upgrade from 8.5 to 9.3

[FernandoSilva]

Hey guys,

I've upgraded my old M10 to 8.5R4.3 and now I intend to upgrade to 9.3R4.4.

But according to 9.3 Release Notes:

Note: You cannot upgrade by more than three releases at a time. For example, if your routing platform is running JUNOS Release 8.5, you can upgrade to JUNOS Release 9.2, but not to JUNOS Release 9.3. As a workaround, first upgrade to JUNOS Release 9.2 and then upgrade to JUNOS Release 9.3.

The problem is that 9.2 is not available anymore at juniper.net!!!

So, how could I do this upgrade?

Tks.

You'll need to contact JTAC for a copy that old.

But my question is that on juniper.net, JUNOS Worlwide software is listed beginning on 8.5 and then going to 9.3, etc.

Why 9.2 is not listed there?

Weird...

Well, I decided to upgrade from 8.5 to 9.3 and it is working very good.

Tks.

Junos 8.5 and Junos 9.3 (and Junos 10.0) are "Extended End Of Life" releases, and so remain active on the site longer.

Junos 9.2 EOL'd 11/12/2009

glad your ugprade worked - the limits described in the release-notes are not hard-coded - those are simply the constraints to what we test against.  So anything outside of that is un-supported if there are issues with the upgrade.
